collection of primitives

Hi, I've been looking all over for documentation, but can't seem to find anything.
I'm trying to map a collection with primitives (Floats), but can't seem to work out how to. I've tried a set, adding the one-to-many with class java.lang.Float, but Float obviously hasn't got any tags and is therefore not mapped. The association fails.

Is there a solition that is so obvious that I've missed it, or do I need to create a workaround solution?

Use collection of values (section 5.3 of hib ref guide)

The collection of values only seems to support many-to-many, is there no option for one-to-many relationships?

No

Code:

<bag name="sizes" table="SIZES" order-by="SIZE ASC">
    <key column="OWNER"/>
    <element column="SIZE" type="integer"/>
</bag>

is kind of a one-to-many relationship.

The section talks about collection of values AND collection of entities (which are naturally mapped as many-to-many).
Your are mismatching
